Surprising Twist: Marine Heatwaves Boost Coastal CO2 Uptake by 11%
In a surprising turn for climate science, a recent analysis has found that marine heatwaves actually increase carbon dioxide (CO2) uptake by coastal waters by an average of 11%, challenging previous assumptions about the ocean's role in global warming. This unexpected boost is particularly strong in the polar and subpolar shelf seas, offering a complex new layer to our understanding of the ocean's fight against rising atmospheric CO2 levels. The study, which looked at data from 1985 to 2020, highlights how these extreme warming events, often seen as purely destructive, can have unforeseen effects on the global carbon budget.
